Recognition of authorised car user

摘要

A procedure for recognising an authorisation for vehicle use has an opto-electronic image processor to identify the user. Depending on at least one identification signal from the processor, locking functions are released to allow vehicle operation. To generate this signal, at least one feature of the would-be user (eg his head) is compared with at least one reference feature that has been stored. The reference features are stored after input of an identification code which contains vehicle data. The image of the would-be user is taken with a CCD camera using a light source that increases the reliability of the identification e.g. one in the near infra-red wavelength.
